What I find particularly refreshing about Accurascale's models is the attention to detail. The packaging, the literature, the body shape, the paint colours and livery details, the running and haulage, the use of Lokpilot functions and the on board / plug and play sound options which can be fitted without having to take the body off.
As with any new model from any manufacturer that has many small details glued on, I'd recommend opening the packaging carefully on a tray. If something has come loose in transit, it'll be found quickly and can be glued back on.
